The Giannelli Ipersport aluminium exhaust system is almost identical to the standard version of the Arrow models for the Honda CBR125R - only the carbon end cap is missing. The assembly is easy to do, but the effect is audible! According to the manufacturer, even small increases in performance at medium rpm should be possible. If you like, you can further optimize the sound by removing the dB-Killer. But be careful, here the EG-BE decays and the volume really increases drastically! Even without, the exhaust system from Gianelli Ipersport offers tuning on a high level thanks to the included rear silencer, middle pipe, holding clamp and mounting material.
